Project description:Nkx2-3 is associated with inflammatory bowel disease (IBD). Nkx2-3 is expressed in microvascular endothelial cells and the muscuularis mucosa of the gastrointestinal tract. Human intestinal microvascular cells (HIMEC) are actively involved in the pathogenesis of IBD and IBD-associated microvascular dysfunction. To understand the cellular function of Nkx2-3 and its potential role underlying IBD pathogenesis, we investigated the genes regulated by Nkx2-3 in HIMEC usin cDNA microarray.

To understand the cellular function of Nkx2-3 and its potential role underlying IBD pathogenesis, we investigated the genes regulated by Nkx2-3 in HIMEC usin cDNA microarray. 2 HIMEC lines (21B and 432) are used in thi study. For each HIMEC lines, either si-Nkx2-3 or contro vector was transfected 2 times to get biological replicates.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
Project description:Analysis of ex vivo isolated lymphatic endothelial cells from the dermis of patients to define type 2 diabetes-induced changes. Results preveal aberrant dermal lymphangiogenesis and provide insight into its role in the pathogenesis of persistent skin inflammation in type 2 diabetes. The ex vivo dLEC transcriptome reveals a dramatic influence of the T2D environment on multiple molecular and cellular processes, mirroring the phenotypic changes seen in T2D affected skin. The positively and negatively correlated dLEC transcripts directly cohere to prolonged inflammatory periods and reduced infectious resistance of patients´ skin. Further, lymphatic vessels might be involved in tissue remodeling processes during T2D induced skin alterations associated with impaired wound healing and altered dermal architecture. Hence, dermal lymphatic vessels might be directly associated with T2D disease promotion. Global gene expression profile of normal dermal lymphatic endothelial cells (ndLECs) compared to dermal lymphatic endothelial cells derived from type 2 diabetic patients (dLECs).Quadruplicate biological samples were analyzed from human lymphatic endothelial cells (4 x diabetic; 4 x non-diabetic). subsets: 1 disease state set (dLECs), 1 control set (ndLECs)
